SHUTTLE.

Application led September 29, 1925.

The present invention relates to spindle shuttles such as are used on silk looms and has for its principal object to provide improved means for holding the core of the bobbin on the spindle.

It is the present practice to use a coiled spring for this purpose which soon becomes loosened at the ends because of the frequent changing of bobbins. M improvement contemplates a novel manner in anchoringl the ends of the spring so as to prevent the saine from becoming loosened.

Vr'ith the above and numerous other objects in view as will appear as the descripr tion proceeds, the invention resides in certain novel features of construction as will be hereinafter more fully described and claimed.

In the drawing- Figure l is a plan View of a shuttle with my improved spindle therein,

F ig. 2 is a sectional elevation of the spindle, and

Fig. 3 is another sectional elevation thereotl taken at right angles to that shown in F ig. 2.

Referring to the drawing in detail, it will be seen that 5 designates the shuttle which is oi" well known formation having mounted therein in the usual manner a spindle 6. Vhis spindle 6 is provided with the heel 7 for being received in the heel end of the shuttle in the usual manner. The shank of the spindle 5 is split longitudinally as is indicated at 8. The slit portion of the shank of the spindle is slightly bulged as at 9 adjacent the tip of the shank, thereby forming a slot.

Serial N o. 59,302.

A spring l0 is coiled about the shank of the spindle 5 between the bulged portion 9 and the butt 7. The end of the spring adjacent the butt .7 is extended through the shank to pierce the same and has its terminal headed as at l1 by means of hammering or the like.

The other end of the spring'is extended I into the opening formed by the slit 8 at the bulged portion 9 and is soldered therein as is indicated at 12. It will thus be seen that the spring wire is prevented from becoming loosened as the bobbins are frequently changed.

It is thought that the construction, utility, and advantages of my invention will now be clearly understood by those skilled in this art without a more detailed description thereof. It is desired, however, to point out that changes in the details of construction may be resorted to without departing from the spirit or scope of the invention as hereinafterl claimed, or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is A shuttle spindle of the class described in-l cluding a slit shank having a portion adjacent its tip bulged to provide a slot, and a wire coiled about the shank of the spindle and having one'end piercing the shank adjacent the butt thereof and the other end extending int-o the slot of the bulged portion and soldered therein.

In testimony whereof I aliix my signature.

FRANK PIZZINO.
